Fiber Optic Adapter is the most essential components in fiber cablings. It also called fibre optic coupler, the function of these fiber adapters is to terminate the end of optical fiber cable by connecting the mating connector. They can come in the version to link a single fiber(simplex), two fibers(duplex) or 4 fibers(quad).
Due to the diversity of fiber optic connector types, There are SC, LC, FC, ST, E2000 adapters. These adapters are designed for single-mode and multimode fiber cable. The single mode fiber coupler is used for longer distances where less data is transferred, while the multimode optical fibre optic cable adapter is for large data transfers at shorter distances. Single mode optical cable adapter especially suitable for networking equipment in different offices or the same data center backbone.
Additionally, all the optical fiber connector adapters have the merits of low insertion loss, good interchangeability, and reproducibility.
